Science Reviewer Presentations #6 Environmental Concerns Flashcards
is a hydrocarbon-containing material formed naturally in the earth’s crust from the remains of dead plants and animals that is extracted and burned as a fuel
FOSSIL FUEL
the main fossil fuels are ____________
coal, crude oil and natural gas
May be burned to provide heat for use directly (such as for cooking or heating), to power engines (such as internal combustion engines in motor vehicles), or to generate electricity
FOSSIL FUEL
When fossil fuels are burned, they emit greenhouse gases like carbon dioxide that trap heat in the earth’s atmosphere and contribute to climate change
CLIMATE CHANGE
when fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain
harmful air pollutants = sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury
AIR POLLUTION
often fossil fuels are extracted from sedimentary rock that lies underwater which means that spills during extraction, like those caused by broken pipes, directly pollute the surrounding water and destroy local aquatic ecosystems.
WATER POLLUTION
To help cut down on air pollution from cars, you can consolidate driving trips, carpool or take public transportation, such as buses and trains. When possible, consider walking or biking instead of driving.
Minimize The Miles
Turning off lights and other electrical appliances when you’re not using them, buying equipment that uses less electricity and limiting your electricity usage.
CONSERVE ENERGY
Leading businesses are taking steps to understand and manage their greenhouse gas emissions by preparing annual greenhouse gas inventories and setting long-term targets to reduce emissions.
MANAGE AND REDUCE EMISSIONS
Buying renewable energy, can help reduce environmental impact while also providing a number of other valuable benefits.
BUY RENEWABLE ENERGY
is the thermal energy in the Earth’s crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions
GEOTHERMAL ENERGY
Geothermal plants remove water and steam from reservoirs within the earth, the land above those reservoirs can sometimes sink slowly over time
POTENTIAL FOR SURFACE INSTABILITY
this is due to alterations in the Earth’s structure as a result of digging
EARTHQUAKES
There’s no solution for Geothermal Energy?
Yes! Cuz it’s 100% environmentally friendly
is a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants.
HYDROELECTRIC ENERGY
